Read Workspace File

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the burden. It does disclose that the operation is a read (safe) and that it is limited to small text files within configured roots. However, it lacks details about error behavior, exact size limits, or whether symbolic links are followed. The transparency is present but minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence. It front-loads the action and includes all essential information without redundancy. Every word contributes to the tool's purpose and constraints. Perfectly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read tool with one parameter and no output schema, the description covers the core requirements: the action, the object type, and the location restriction. It could be more complete by specifying error outcomes or the 'small' size threshold, but the essential context for invoking the tool is present. Slight gap in usage guidance is already reflected in that dimension.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already describes the only parameter (filePath) with 100% coverage, so the baseline is 3. The description adds a note about 'small text file' and 'configured workspace roots,' but these are tool-level constraints, not parameter-specific semantics. No additional meaning is provided for filePath beyond what the schema already states.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb (Read) and a clear resource ('small text file inside configured Zynx workspace roots'). It differentiates from sibling tools like list_workspace_files (listing) and query_table (querying). The scope is clearly defined, making the tool's purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage context is implied rather than explicit. The description indicates what the tool does but does not state when to use it over alternatives (e.g., when to read a file vs list files or query a table). There is no mention of exclusions or prerequisites. This is consistent with a 'minimum viable' level of guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
